Abstract
The utility model discloses a nanometer alloy wear-resistant plate for railway screen scarifier, comprising a wear-resistant plate, a groove and a wear-resistant sheet, wherein the plane and the side surface of the wear-resistant plate are provided with straight grooves, the wear-resistant sheet is embedded in the groove and is bonded and fixed by a high-frequency brazing welding bonding technology, and a T-shaped nanometer powder sintered hard alloy sheet is embedded in the groove; and then the L-shaped plate is bonded and fixed by an original high-frequency brazing welding adhesion technology, so that the wear resistance and impact resistance of the L-shaped plate are greatly enhanced, the plate surface is stressed more reasonably, and the wear-resistant nano alloy is combined with the plate surface more tightly and firmly, so that the L-shaped plate has better wear resistance, impact resistance and toughness, the service life of the L-shaped plate is prolonged by adopting a nano powder sintered hard alloy material with excellent wear resistance and toughness, and the L-shaped plate has the advantages of wear resistance, impact resistance, corrosion resistance and the like.
Description
Technical Field
The utility model belongs to powerful wear-resistant material field especially relates to a railway is nanometer alloy antifriction plate for sieve cleaning machine.
Background
An L1469 template for a railway line maintenance cleaning vehicle is a main part and a vulnerable part used in the railway line cleaning process. At present, in the selection of parent metal of an L-shaped plate for railway line maintenance and screening in China, the parent metal of 65Mn or common cast iron (the parent metal does not contain any wear-resistant and toughness-enhancing alloy elements) is generally adopted, and the defects that the tensile strength, the yield strength, the reduction of area and the hardness of the parent metal are weak and easy to break, and the service mileage of the L-shaped plate is about 3 kilometers, so that the service life is short, the cost is high, the efficiency is low, and the labor intensity of workers is high. The L-shaped plate which is generally used in the past has certain hardness and wear resistance after being subjected to heat treatment, but in the working environment of a railway screen scarifier, the wear-resisting plate is frequently vibrated due to the movement of the raking teeth and the raking chains, and strong uninterrupted wear of the steel plate, the raking chain stones and the steel plate is generated due to the irregular shape of stones, so that the temperature of the steel plate is increased, the wear resistance is rapidly reduced, and the steel plate is worn quickly.
Disclosure of Invention
The utility model aims at providing a railway cleaning machine nanometer alloy antifriction plate that has good wearability, long service life, sufficient toughness and impact resistance again.
In order to realize the purpose, the utility model provides the following technical scheme: the utility model provides a railway is nano-alloy antifriction plate for sieve cleaning machine, includes antifriction plate, recess, wear pad, wear plate plane and side are seted up straight recess, inlay the wear pad in the recess and bond fixedly through the high frequency welding technique of brazing.
Preferably, the wear-resisting plate is an L-shaped plate made of a 35GrMo steel base material.
Preferably, the wear-resistant plate is a T-shaped nano powder sintered hard alloy plate.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model has simple structure and convenient use, adopts the unique straight groove opened on the plane of the L-shaped plate, and the groove is paved with and embedded with the wear-resistant nano powder sintered hard alloy sheet; the side surface of the plate is provided with a narrow groove, and a T-shaped nano powder sintered hard alloy sheet is embedded in the groove; then bonding and fixing the L-shaped plate by an original high-frequency brazing welding technology, greatly enhancing the wear resistance and the impact resistance of the L-shaped plate, leading the stress of the plate surface to be more reasonable, leading the combination of the wear-resistant nano alloy and the plate surface to be more compact and firmer, leading the L-shaped plate to have better wear resistance, impact resistance and toughness, leading the service life of the L-shaped plate to be prolonged by adopting the nano powder sintered hard alloy material with good wear resistance and toughness, having the advantages of wear resistance, impact resistance, corrosion resistance and the like,

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a railway is nanometer alloy antifriction plate for sieve cleaning machine which characterized in that: the method has the advantages that induced current is selected as a heat source, a workpiece is heated in a local heating mode, heating temperature can be accurately controlled, the brazing temperature can be reduced progressively, brazing filler metal is brazed in sequence, and welding quality can be improved. The wear-resisting plate 1 is characterized in that an L-shaped plate of a 35GrMo steel base material is selected, compared with an L-shaped plate of a commonly adopted nodular cast iron base material, the L-shaped plate of the 35GrMo steel base material has the advantages that the tensile strength, the yield strength, the reduction of area and the hardness are obviously superior to those of the L-shaped plate of the nodular cast iron base material, and the wear-resisting plate has unique excellent quality. The wear-resistant plate 3 adopts a T-shaped nano powder sintered hard alloy plate, when the grain size of the hard alloy is less than 1um, the double-high characteristic is generated, namely, the hardness and the strength are greatly increased, and the characteristic becomes more prominent along with the grain refinement. The research of the nano alloy is the only way to solve the contradiction of the hardness and the strength of the material, and the nano hard alloy not only realizes the unification of high hardness and high strength, but also has higher wear resistance.
